Slow-setting additives are sometimes used to reduce the effect of hot air on concrete trapping, sometimes to prolong traction time on bulky tasks such as large concrete dams or to pump concrete over long distances or to transport ready-mixed concrete over long distances.
Properties and effects:
- Delay in the initial and final setting of concrete
- Possibility of concreting in tropical areas
- Possibility of concreting in windy areas
- Ability to build and transport concrete over long distances
- Increasing the performance time and workability of concrete
- Decreased concrete temperature in bulk concreting
- Reduce the risk of cold seams in high-volume concreting
- Increasing the vibration time of concrete
- Prevention of surface and thermal cracks in concrete
- Compatible with Portland Cement
- Increase the strength of concrete in the long run
Application:
- Massive and semi-bulky concretes such as dam construction and bridges, etc.
- Suitable for controlling thermal gradient resulting from cement trapping
- Suitable for projects that require concrete trapping control in the early and final stages.
- Suitable for concreting in tropical areas
- Suitable for concreting with more than normal distance
- Suitable for making pumpable concrete
- Construction and transportation of concrete over long distances and far from concrete plants
